258 MPFI mod

I have the option of upgrading the cj-7 258 from a weber carb to a TBI or MPFI. custom MPFI will build me and fully programable on the fly MPFI system for $1400 using my old head with a modified 4.0 intake and all associated parts or a TBI not programable for $1100 which one would you go with and why?

1984 CJ-7 offroad special loves to get dirty and play rough. unlike the girls I meet
258 rebuilt with torquer cam/ weber 32/36 carb, HEI ignition ,headers 4 in lift AMC 20 detroit rear locked and trussed / tru trax front 4:56 Gears ,solid axles on 35's

New seats, carpet, console, roll bar pad, seat belts,dash, flares, windshield, seals, tire carrier and more!

MPFI all the way...but remember, you'll need a $250 vibration dampener that they didn't tell you about.

I used to own two CJ's...Perhaps a 3rd is in the future?
